The invention belongs to the technical field of rubber molding. The invention provides a polyurethane cover rubber. Different modifiers are added to the raw polyurethane rubber to improve the performance of the polyurethane rubber. On the premise of improving the oil resistance, the excellent wear resistance is still retained, so that the polyurethane The application range of rubber is wider; at the same time, the m-a white system is added to it, so that the modified polyurethane rubber can have better adhesion to the cord or steel wire, prevent separation during use, and ensure the quality of the product. The invention also provides the preparation method of the conveyor belt, which comprises the steps of banburying the cover rubber and the sticker independently, and then controlling the size of the cover sticker and the sticker after the banburying through a calendering process, so that the cover rubber and the sticker can be fully fitted with the skeleton material. A semi-finished product is obtained; finally, a wear-resistant and oil-resistant polyurethane conveyor belt is obtained through a corresponding vulcanization process. The present invention improves the quality of the conveying belt through a simple production process, and ensures the use in the conveying process. |
